Introduction to Diode IR

Diode IR is a semiconductor device that emits or detects infrared radiation. It operates on the principle of electron-hole recombination within the semiconductor material. When a diode is forward biased, electrons and holes are injected into the depletion region, and as they recombine, they release energy in the form of infrared radiation. Conversely, when a diode is reverse biased, it can detect infrared radiation by responding to the photons that strike its surface.
